    Yes it could be. However I don't have this problem with my PS3 : when I set the output to 1080p, it's immediately usable on my TV. And I have no issue powering on my PS3 first.
    So I really wonder why my PS3 gets it right and why my Ubuntu/Intel HTPC gets it wrong.

    I have found an approximate modeline which allows X to start in 1080p but it's not perfect, so I still have to adjust the screen shape under XBMC.

    Not sure it's Intel's fault though (Ubuntu 12.04) I also have a TV with wrong EDID and it's quite painful to setup the HTPC with the accurate mode

    Good news but

    Very good news indeed for HTPC users.

    I also have a TV with wrong EDID and it's quite painful to setup the HTPC with the accurate mode ; fortunately XBMC helps, but it forgets the settings regularly.
    I do not understand why it's so painfull to make a linux HTPC work like any video device : plug the HDMI to the amplifier, choose the output definition, nothing more should be required from the user.

    To be fair, the article makes it sound like this patch changes more than it does - all it does is send the audio through without remapping channels. The net result is still that DTS-MA/TrueHD work properly after fixing this bug, though (if you screw with channel mapping, the receiver is unable to decode the compressed stream).
    This patch is part of a series of patches. With the current ALSA git tree both TrueHD and DTS-HD are working fine on my Ivy Bridge CPU. Channel mappings are also fine. So yes, I think this patch is a great step forward for Intel HTPC owners

    • OpenCL Compute
    • QuickSync
    • OpenGL 4.x
    • Optimus Style GPU switching
    • Performance
    Have you been watching recent progress?

    Yes, DTS-MA and TrueHD are the lossless formats used on BluRay. To be fair, the article makes it sound like this patch changes more than it does - all it does is send the audio through without remapping channels. The net result is still that DTS-MA/TrueHD work properly after fixing this bug, though (if you screw with channel mapping, the receiver is unable to decode the compressed stream).
